Canada's Gabriel Diallo retires due to injury in opening match at French Open

Gabriel Diallo is out of the French Open.

The Montreal native retired due to injury from his opening-round match against Australian James Duckworth on Sunday at the tennis Grand Slam event. Duckworth was leading 6-3, 4-1.

Diallo went without an ace and break-point opportunity before exiting the match.

Duckworth had three aces and converted on three of his five break-point chances.

Canadian men Felix Auger-Aliassime and Denis Shapovalov are set to play their opening matches on Tuesday.

On the women's side, Leylah Fernandez opens her tournament on Monday and Victoria Mboko plays on Tuesday.

Sunday's opening day saw players coping with high temperatures of 33 degrees Celsius (91 Fahrenheit) — with the intense heat contributing to Frenchman Arthur Gea taking an emergency bathroom break early into his first-round loss to No. 13 Karen Khachanov on Court Suzanne-Lenglen.

Spectators folded newspapers in half and fanned themselves to keep cool as players on court attempted to stay hydrated.

The opening match on Court Philippe-Chatrier saw No. 11 Belinda Bencic beating Sinja Kraus 6-2, 6-3 and 2024 runner-up Alexander Zverev followed with a 6-3, 6-4, 6-2 win against Benjamin Bonzi. The second-seeded German plays unseeded Tomas Machac next.

The night match on Chatrier features three-time champion Novak Djokovic against Giovanni Mpetshi Perricard.

Two days after his 39th birthday, Djokovic will play a men's record 82nd Grand Slam tournament — one more than Roger Federer and Feliciano Lopez.
